The Casper Police Department is still investigating a fight at the Gaslight Social which left a man severely injured over a month ago, and investigators are asking for the public's help in identifying two people who may have witnessed the incident.

Alvaro Proa, 21, may have had a knife in his possession when he reportedly instigated a fight with a bouncer during the Gaslight Social's Halloween costume party on Oct. 28.

Proa was severely beaten and had to be flown to a Denver hospital; he continues to recover from his injuries. Charges have not been filed in connection with the incident.

Police have been trying to get in touch with people who were at the Gaslight Social that night and may have witnessed the incident.

Anyone who knows the people pictured is asked to call Detective Stedillie at 307-235-8371.
